Screen is nice, but I would give up a line or two of real estate on my monitor for a bit more context about where exactly I am. Yes, I know you can name windows and even keep the window name visible for the current screen, but I'd love to have tabs at the bottom, always visible (or toggle-able with a key-stroke) that shows all open sessions and where you are.

This should be possible without a gui, keeping things VT100.
